I wouldn’t expect that to cause a significant issue, but we can send you a replacement just to have.
I think that you could be right that we’re looking for something like that.
If you extend all the belts and then retract them again, what numbers does it print out? We would expect them to all be close to zero.
what a day!
I took Maslow apart. That top most/top left arm was the problem. I opened it up and made sure everything was to instruction - which it was. No magnet misplacement. No belt misplacement. I put the unit back together swapping out the top most arm with the bottom most and BAM!
I am back up and calibrating! Now were the screws too tight. Was the belt binding on the belt guard. I don’t know.
I’m calling it a day! Thanks for your help.
Excellent work!
Back to square 1… I tried to calibrate again today and failed. This seems to be an intermittent problem. I conclude one of the arm’s sensors is bad but I don’t know where.
I know I was able to calibrate and cut. However, after that I was getting a red light. The red light was appropriately letting me know something was WRONG.
Looking back in the thread, I can see there was a discrepancy in arm #2 after clicking the Retract all…
[MSG:INFO: 0 pulled tight with offset -1568.027]
[MSG:INFO: 1 pulled tight with offset -1695.829]
[MSG:INFO: 3 pulled tight with offset -1822.944]
[MSG:INFO: 2 pulled tight with offset 1332.241]
I’ve concluded the arms are numbered as in the picture below. Top left (2), Top right (1), Bottom left (3), Bottom right (0).
There was a problem in Top Left #2 belt. So I disassembled and made sure the mechanics looked right, which they did. I moved arm #2 to the bottom of the stack and everything else up. Arm #2 was now in the #3 spot - bottom left.
I pulled the belts out at different length as seen in the picture below. And again from the numbers, Arm #3 (formerly #2) has significantly different offset from the rest.
[MSG:INFO: 1 pulled tight with offset 0.032]
[MSG:INFO: 3 pulled tight with offset 388.507]
[MSG:INFO: 2 pulled tight with offset 0.021]
[MSG:INFO: 0 pulled tight with offset 0.032]
I was able to calibrate last night and this morning back to square 1.
I don’t know where the force on the belt is being measured. I don’t know where the belt distance is being measure - I assume associated with the magnet N/S rotations. The magnet is in the right spot. I wonder if there is a problem with the magnet/ethernet chip. I changed the black ethernet wire with another and don’t like the problem is there. The PCB could be the problem but I wouldn’t know how to troubleshoot it. I would think if the PCB would’ve been the problem the error would have stayed in the Top Left location.
That’s my thoughts.

This is 100% the issue. We need to get to the bottom of what is going on with that arm.
Is it possible that the magnet is rotating in place ie the glue is not holding it still? I’ve had issues similar in the past when I had a magnet that wasn’t fully glued into place.
I think that’ is excellent deduction.
They’re pretty reliable but not perfect. If you want to test we can send you an extra encoder board check that.
My hope is that it’s a lose magnet because that’s the easiest and quickest to fix, but it seems like at least we’ve tracked the issue down to a repeatable issue which we can solve which is good.
